Análisis de la implementación Schema.org en el repositorio RODERIC e impacto en el posicionamiento en Google y Google Scholar
2021
espanolSe presenta la implementacion de Schema.org en el repositorio RODERIC de la Universitat de Valencia. Para el analisis del impacto de la implementacion se han definido ocho indicadores que se han analizado en Google Search y Google Scholar segun el caso: visitas, visitas a registros bibliograficos, documentos descargados, impresiones, clics, CTR, posicion media en la SERP y posicion en la SERP que fueron analizados durante dos periodos consecutivos de un ano, antes y despues de la implementacion. Los resultados obtenidos muestran resultados desiguales para ambos buscadores. En el caso de Google Search, a pesar de conseguirse un incremento considerable en el numero de impresiones (21,0…
The Hints from the Crowd Project
2013
Can the crowd be a source of information? Is it possible to receive useful hints from comments, blogs and product reviews? In the era of Web 2.0, people are allowed to give their opinion about everything such as movies, hotels, etc.. These reviews are social knowledge, that can be exploited to suggest possibly interesting items to other people. The goal of the Hints From the Crowd HFC project is to build a NoSQL database system for large collections of product reviews; the database is queried by expressing a natural language sentence; the result is a list of products ranked based on the relevance of reviews w.r.t. the natural language sentence. The best ranked products in the result list ca…
Search Interfaces and Learning about Controversial Topics
2019
Search engine results pages (SERPs) are a frequent gateway to Internet content. Prior research has extensively documented strong effects of SERPs (e.g. rank order or the spatial distribution of the results) on users' attention to and selection of particular Web pages [1,2]. In the context of Web search, a common user behavior is the 'top link' or 'Google trust' heuristic, that is, the inspection and selection of only the first few search results presented by the search engine, without evaluating all other search results available. This heuristic behavior allows users to find information in an efficient way, as search engines tend to provide relevant documents on top of the list, especially …
Temporal Logic To Query Semantic Graphs Using The Model Checking Method
2012
International audience; Semantic interoperability problems have found their solutions due to the use of languages and techniques from the Semantic Web. The proliferations of ontologies and meta-information have improved the understanding of information and the relevance of search engine responses. However, the construction of semantic graphs is a source of numerous errors of interpretation or modeling, and scalability remains a major problem. The processing of large semantic graphs is a limit to the use of semantics in current information systems. The work presented in this paper is part of a new research at the border of two areas: the semantic web and the model checking. This line of rese…
Sabiedrībā aktuālu tēmu vizualizācija, izmantojot sociālo tīklu un tīmekļa meklētāju datus
2015
Sabiedrībā risinās notikumi, kuri ir aktuāli un kuriem seko līdzi ikviens mūsdienīgs tīmekļa lietotājs. Pateicoties tieši moderno tehnoloģiju straujajai attīstībai, sabiedrībā aktuālo iespējams uzzināt praktiski vienlaicīgi ar tā risināšanās gaitu. Galvenie darba mērķi ir salīdzināt un izpētīt populārākos tīmekļu meklētājus un sociālos tīklus, kuri nodrošina informācijas piegādi lielākajai daļai lietotāju. Izmantojot tīmekļu meklētāju un sociālo tīklus, iegūtos datus, veikt analīzi par sabiedrībā aktuālo tēmu ieguves iespējām. Balstoties uz izdarītajiem secinājumiem, ievākt un attēlot pieejamo informāciju interneta vietnē. Galvenais uzsvars tiek likts uz vēsturisko datu pieejamību un inform…
A Conversational Agent Based on a Conceptual Interpretation of a Data Driven Semantic Space
2005
In this work we propose an interpretation of the LSA framework which leads to a data-driven “conceptual” space creation suitable for an “intuitive” conversational agent. The proposed approach allows overcoming the limitations of traditional, rule-based, chat-bots, leading to a more natural dialogue.

Reliability Analysis of Three Homogeneous Fault-tolerant Inverter Topologies
2016
Abstract—In this article, non-redundant fault-tolerant inverter topologies are addressed. A novel fault-tolerant control strategy which enhances performances during post-fault operation is proposed. Benefits from the proposed strategy over conventional fault-tolerant topologies are investigated in terms of system reliability. Cost, post-fault performances, and system reliability of the proposed solution are compared with both a conventional triac-based fault-tolerant inverter and a T-type inverter. The reliability analysis of each selected configuration is carried out by means of Markov chains. The analysis is validated through a comparison of reliability and sensitivity curves. As shown by…
Enabling Searches on Wavelengths in a Hyperspectral Indices Database
2018
Abstract. Spectral indices derived from hyperspectral reflectance measurements are powerful tools to estimate physical parameters in a non-destructive and precise way for several fields of applications, among others vegetation health analysis, coastal and deep water constituents, geology, and atmosphere composition. In the last years, several micro-hyperspectral sensors have appeared, with both full-frame and push-broom acquisition technologies, while in the near future several hyperspectral spaceborne missions are planned to be launched. This is fostering the use of hyperspectral data in basic and applied research causing a large number of spectral indices to be defined and used in various…
Electrochemical Oxidation of Hf-Nb Alloys as a Valuable Route to Prepare Mixed Oxides of Tailored Dielectric Properties
2018
Metal oxides with high dielectric constant are extensively studied in the frame of substituting SiO2 as gate dielectric in nanoelectronic devices. Here, high-k mixed HfO2/Nb2O5 oxides are prepared by a facile electrochemical route starting from sputtering-deposited Hf–Nb alloys with several compositions. Transmission electron microscopy, grazing incidence X-ray diffraction, and glow discharge optical emission spectroscopy are employed to study the oxide structures, disclosing a crystalline–amorphous transition of the electrochemically prepared oxides by increasing the Nb content. Photo-electrochemical measurements allow the observation of optical transitions ascribed to localized states ins…
